UNTTED STATES PATENT OFFTCE.

MODE OF ADJUSTING- BLINDS rlO WINDOWS, &c.

Specicaton of Letters Patent No. 13,398, dated August '7, 1855.

To all whom it may concern Be it known that we, C. E. PARKER, of Boston, in the county of Suffolk and St-ate of Massachusetts, and JOSEPH SANGER, of Vatertown, in the county of Middlesex and State of Massachusetts, have invented a new and Improved Mode of Flanging or Adjusting Blinds to Vindows; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a longitudinal vertical section of a window casing, with our improvement applied to it, Fig. 2, shows the plane of section. Fig. 2, is a transverse vertical section of ditto, y y, Fig. l, showing the plane of section.

Similar letters of reference indicate corresponding parts in the two figures.

The nature of our invention consists in having ropes or chains attached to the two parts of the blind in a peculiar way as will be presently shown, whereby either or both parts of the blind may be raised and lowered from the inner side of the casing within the apartment,.and without raising or opening the sashes.

To enable others skilled in the art to fully understand and construct our invention, we will proceed to describe it.

A, represents a window casing, in which the sashes B, B, are fitted in the usual way, the sashes having' cords, a, and weights, attached, as shown in Fig. 2.

The stiles of the window casing A, are made somewhat wider than usual, so as to afford room or space to t the two parts C, C, of the blind in grooves in the stiles precisely similar to the sashes B, B, which as before stated are adjusted or litted in the casing in the usual manner. The casing A, is pro-vided with boxes D, D, one at each side, and arranged in the same way as the boxes of all casings in which weighted or balanced sashes are tted. The upper ends of these boxes directly over the two parts of the blind is in communication with a recess E, made in the building immediately over the casing, and of a height and breadth corresponding with the parts of the sashes. This recess may be formed of a box F, attached to the upper part of the casing, and the masonry tted around it, see Fig. 2.

At the lower parts of each box D, there are placed two pulleys, 0, 0, and a pulley, d, is secured in the upper part of the back side of the box F, a pulley, d, at each side of the box, and a rope or chain, e, passes around the pulleys c, c, d, at each side of the casing. A weight G, is secured to each rope or chain, e, and tubes, f, serve as guides to the ropes or chains where they pass from the upper ends of the boxes D, D, to the upper end of the box F, see Fig. 2. The ropes or chains, e, e, pass on the outer side of the casing A, as shown in Fig. 2. This side of the casing is within the apartment or house, so that the ropes or chains, e, e, may be operated from within as will be presently shown.

To each rope or chain, e, there is attached a rope or chain, g. These ropes or chains, g, pass over pulleys, i1., h, at the upper part of the box F, and pass over pulleys z', z', at the center of the upper part of the box F, and are then attached to the two parts C, C, of the blind.

By the above improvement it will be seen that the parts 0, c, of the blind may be raised and' lowered by operating the ropes or chains e, e, at the outer side of the casing and within the apartment- Vhen both of the parts c, are fully raised they lit within the box F, above the casing A. The sashes do not require to be raised as is now the case, in order to adjust the blinds. And in cases where double sashes are used, the outer sashes may be applied to the outer edges of the sides or stiles of the casing, the blind being between the two pairs of sashes. Outer sashes are often applied during the winter season and the ordinary blinds removed. But by our improvement the blind may remain and be operated equally as well and fully protected from the weather.

7e do not claim itting blinds in grooves in the casing and having a. recess or box formed over the casing to receive the blinds, for this is not new, iron doors and shutters having been previously so arranged, but,

That we do claim as new and desire to secure by Letters Patent, is,

Attaching the ropes or chains e, e, g, g, to the two parts C, C, of the blind, so that a portion of the ropes or chains e, e, will pass on the outer sides of the casing A, and within the apartment or house, and thereby allow the parts C, c, of the blind, to be adjusted as desired, without raising or opening the sashes, as herein shown and describd- CHARLES E. PARKER.
